Salt from green beans Name: Ashni Couprie and Dennise Susanto Class: 5c Introduction From previous experiments we ’ve learned that salt is extracted from green beans. To be more specific: salt is extracted from when the beans are cooked in water in which salt has been dissolved. This experiment is based upon the osmoses theory. According to this theory the cell walls of the green beans are what we call a semi permeable membrane. This membrane only lets water through and not the substance

INTRODUCTION Since 1952 a subsidiary of British Company for chemical manufacturer was established in Ghana‚ named Wilson Chemical (Ghana) Ltd. There were three reasons for its success: 1. Fertilizer as the primary product in an agricultural based economy 2. The company employed many natives in top positions 3. Appointed a native Ghanaian graduated from Oxford‚ Joseph Okono‚ as the president of Wilson Chemical (Ghana) Ltd. Under Mr. Okono’s management‚ the company achieved a great success in sales and

Intercontinental University Aspects of Psychology Individual Project # 2 Experiments and Adaption July 30‚ 2012 ABSTRACT This paper is explaining five experiments; the process and results. It talks about sensory adaptation and how adaptation is evident in each of the experimental results. It also provides a comprehensive description of the sensory systems in the experiments that I performed. Before starting the four experiments‚ I had to remember that I had to keep in mind that there are five

The Bobo Experiment was performed in 1961 by Albert Bandura to try and prove that people‚ especially children‚ learn their social skills and behaviors from copying or mimicking adults in their lives rather than through heredity genes. Bandura wanted to show‚ by using aggressive and non-aggressive adult-actors‚ that a child would be apt to replicate and learn from the behavior of a trusted adult (Shuttleworth‚ M. 2008). These issues have been present for many years‚ even before the media used these

The purpose of this experiment was to test the tonicity of potato cells. The potato cells were placed in different test tubes with water and were left there for 15 minutes. The percent change in mass is then used to determine if the cells lost or gained water‚ therefore determining the tonicity of the cell. Although it was a brief short time‚ the final results showed that the more water the potatoes were placed in‚ the more hypotonic the potato becomes. Tonicity is stated to be the state of a solution

Biotechnology‚ Mapua Institute of Technology ABSTRACT In this experiment‚ solubility class of various organic compounds are to be determined. The main objective of the experiment is to identify an unknown compound through the use of preliminary tests such as examination of physical state‚ color‚ odor‚ and ignition properties. Also‚ solubility tests were used to further examine an unknown compound’s solubility class. In this experiment‚ the apparatus used are micro test tubes and droppers for mixing

To confirm this assumption‚ the experimenter‚ Victor Seo has developed an experiment to prove the hypothesis: “people who consume lots of chocolate will produce more acne than people eat less chocolate. 400 students of teenagers with grades ranging from 9 to 11 will be examined divided into four groups each consuming 1 bar‚ 3 bars‚ 6 bars‚ or 10 bars daily. This experiment will remain over a time period of a month. Meals will be served in equal amounts and the amounts of

Stanley Milgram: ’electric shock’ experiments (1963) - also showed the power of the situation in influencing behaviour. 65% of people could be easily induced into giving a stranger an electric shock of 450V (enough to kill someone). 100% of people could be influenced into giving a 275V shock.
